To @ZZ whom t may concern.-

Be it known that I, SERAPHIN Klares, a citizen of Germany, residing atBrooklyn, in the county of Kings and State of New York, have inventednew and useful Improvements in Presses for Making Screw-Insulators, ofwhich The object of this invention is to provide a sulators fortelegraph-lines and the like can be rapidly and accurately carried on;and the invention resides in the novel features of construction setforth inthe following specification and claims and illustrated in theannexed drawings, in which- Figure lis a sectional side elevation of thepress. Fig. 2 is a front elevation of Fig. 1.

tion along m fr, Fig. 3. Fig. 5 shows a fillingpiece. Fig. 6 is a detailview of a spindle.

a. filling-piece ready to be slipped onto the screw-plunger. Fig. 8 is adetail view of an air-blast or cooling-tube.

The base 1 bybeing mounted on wheels 2 enables the device to be readilymoved to any desired point. From the base 1 rise legs 3, carrying a topplate 4, in which is fixed a standard 5. A platform or support 6,carrying a suitable number of molds 7, is rotatable about standard 5.This support 6 when rotated a sufficient distance to bring one oranother of the molds 7 into operative position can be locked in positionby a spring catch or detent 8 engaging one or another of the rey When amold isfilled with the molten glass or material for the insulator 10,Fig. 4, a screwplunger is forcedA into such mass to forma screw-threadtherein. Said screw-plunger is shown as consisting of a screw-thread Aand stem B, and the stem B can be detachably connected to or seated inthe hollow or tubular end of the actuating-rod 11, guided in arms 13 and14, extending from standard 5. To this actuating-rod is secured across-head 15, jointed at 16 to an arm 17` extending from lever 18 and19. The actuation of lever 18 and 19 with arm 17 will actuate cross-head15 with actuating-rod 11. v

The stem B of screw-plunger A B can be detachably connected toactuating-rod 11 by into the mass 10, while on the return stroke of rod11 the screw-plunger is to be left inserted in the mass, either by thecatch 2O being withdrawn by hand or by the engaging end of the catch 20being formed at such an angle or incline that on the movement of rod 11away from mold 7 the catch will slip or auitomatically move out ofengagement with the tube B. y

Y The former 24, with follower 25, moves with the actuating-rod 11toward and from the mold 7. The former and follower are secured to rods26, sliding in arm 27, extending from arm 14 and extending looselythrough crosshead 15, being prevented from falling or pass ing out ofengagement with the latter by collars 28, secured to the rods 26. Thecrosshead 15, when moving toward a mold, presses on springs 29, coiledabout the rods 26 and acting against collars 30, fastened to said rods,so that the motion of the cross-head 15 toward a mold will move or holdthe former and follower toward such mold by a yielding or springpressure.

The arm 19 of the lever 18 and 19 is Weighted and it is noticed that themovement of arm `18 against the action of the weighted arm 19 will movethe rod 11, with the former 24 and follower 25, toward a mold, while theweighted arm 19,'on the release of arm 18, can be made to automaticallyreturn the rod 11 with the former and follower. The lever 18 and 19 isfulcrumed at 31 to links or rods 32, jointed at33 to arm 14.

From standard 5 extends an arm C, Fig. 6, to which is secured a rod 54,`which carries an arm 34, in which is guided the sliding and rotary rodor spindle 35, jointed at 36 to link `37, which is jointed at 38 tolever 39 and 40,

stem B of a screw-plunger A B. A screw or fastening 44 enables the stemB to be secured to spindle 35.

From standard 5 extends an arm 45, on which a filling vessel or measure46 is rotatably mounted, so that it can be tilted or up- When thesupport 6 is locked by detent 8, a mold 7 is under the measure 46, sothat on tilting the latter the molten mattei' from the measure will runinto the mold, the measure being conveniently calculated to hold such aquantity of material as is required to properly supply the mold.

The operation of the device is as follows: Supposing the device to be atrest, with the rod ll and spindle 35 raised and the support 6, locked bydetent 8, engaging one ot the recesses 9, a mold 71's then under themeasure 46 and can be charged from the latter. The support 6 .is thenrotated in the direction of arrow 48, Fig. 3, so as to bring the chargedmoldunder the vactuating-rod l1, whereupon the support 6 is again lockedand the rod `11 is then actuated by lever 18 and 19 to force thescrew-plunger into the mass in the mold, said screw-plunger, as alreadyseen, remaining in the mass on the return of the rod 11. VOn the stem Bof the screw-plunger is then slipped a filling-piece 49 as soon as thestem B has passed sufficiently far from under rod 1l to be accessible,said filling-piece beingintended to prevent the soft mass from sinkingback'against stem B, while the mold with the screw-plunger therein iscarried toward the spindle 35 by the continued rotation of support 6 inthe direction of arrow4S. This filling-piece 49 is withdrawn or removedbefore the mold comes under spindle 35. Vhen the mold arrives under thespindle 35, the table 6 is again locked and lever 39 and 40 is thenactuated to move the spindle 35 toward the mold, so that the spindle 35slips over the stern B of the screw-plunger sticking in said mold.4 Thestem B is then secured to spindle 35 by the screw or fastening 44, sothat on the spindle 35 being rotated in the proper direction thescrew-plunger turning with the spindle will screw outof the massorinsulator in the mold, said mass having become sufficiently set toretain its form with the screw-thread formed by the screw-plunger. Onthe mold being now opened the insulator can be removed therefrom andthemold can be again charged from measure 46.

By having a series of molds on support 6, which molds successively arecharged by the measure 46 and successively provided with screw-plungersby rod 1l, which screw-plungers are successively withdrawn or unscrewedby spindle 35, the operation of forming the insulators can be rapidlycarried on, while the uniform charging of the molds by measure 46 willenable accurate work to be attained.

In addition to lock 8 the support 6. may be locked on the movement ofleverarm 39 toward said support by a detent rod or slide 50, guided inarms 5l, extending from standard 5 and connected lto arm 52, extendingfrom lever-arm 39. On the movement of lever-arm 39 toward support 6 thedetent or lock 50 engages one of the recesses or shoulders 53, Fig. 3,in table 6, so as to hold or loclethe latter until the lever-arm 39returns.

The actuating-rod 1l and spindle 35, while supported by the samestandard 5, are independent of one another, so that each of these partscan be respectively operated at such time and with such rapidity asrequired.

To prevent overheating of the follower and plunger a tubular ring 55,Figs. 4 and 8, is suitably applied about the plunger, which ring55,receiving airoracooling-blast through conduit or hose 56, will ej ectsaid air through suitable jet-openings in tube 55,'so thatthis air-blastwill cool or prevent overheating.

The ring 55 is in the form of a tube and is mounted on the follower andsurrounds the plunger, whereby `the jet or blast tube is always incorrect position to operate upon the plunger and follower, incontradistinction to being arranged in such manner that it only operateson the plunger at certain points.
